Title: Covering element for chimney, and associated cowl
IPC: F23J13/00
Filed: 1988-06-18
Abstract: The covering element (2) for a chimney serves to cover the chimney head of chimneys which are brick-lined or made of chimney elements. In order to avoid cold bridges and the associated extremely disadvantageous condensate formation in the waste gas outlet region of the chimney, the covering element (2) has a heat-insulating part (3) consisting of heat-insulating material, which covers the upwardly directed end face of the chimney head. This heat-insulating part (3) is surrounded on its upper, inner and outer side (4, 5, 6) by a water- impervious covering (7) and extends from the outside of the expansion joint sleeve (10) as far as over the outer edge of the chimney. The expansion joint sleeve (10) is rigidly connected in a thermally insulated manner, via a practically non-heat-conducting silicone rubber layer (28), to the downwardly directed surface of the upper side (4) of the covering (7). The underside of the heat-insulating material (3) is supported by a copper net (8) or a number of copper bands and thus brushed over, over practically its entire surface, by the circulation air which flows through the rear ventilation ducts (13) and escapes into the open behind the drip sheet (9). <IMAGE>

Title: Method for treating electrical steel by electroetching and electrical steel having permanent domain refinement
IPC: C25F3/14
Filed: 1989-03-17
Abstract: Permanent domain refinement of grain oriented electrical steep strip (16) is obtained in a high speed two-stage process. The process removes the glass in narrow regions (17) which just expose the base metal. An electrolytic etch is then used to deepen the regions (17) into the base metal and minimize damage to the remaining glass film. Control of acid concentration and temperature in the electrolytic bath allows a greater increase in productivity. A further feature of the process is the use of permeability measurements to optimize the depth of the etched regions. The improved core loss produced by the process will survive a stress relief anneal.

Abstract: Bei einer Steckverbindung wird die Eingriffslage des Stecker­
teils im komplementären Buchsenteil durch einen U-förmigen 
Federbügel verriegelt. Verkröpfte Endabschnitte der Bügel­
schenkel dienen zum Hintergreifen von Rastnasen des einge­
führten Steckerteils und durchgreifen Durchbrüche in einem 
hülsenförmigen Gehäuse des Buchsenteils, wo der Federbügel 
gelagert ist. Die Entriegelung des Steckerteils erfolgt 
durch eine Spreizung der Bügelschenkel, welche die Rast­
abschnitte aus der Einführungsbahn des Steckerteils heraus­
bewegt. Um dies bequem und auch unter ungünstigeren Raum­
verhältnissen auszuführen, wird vorgeschlagen, den Feder­
bügel in seiner ganzen Länge als Hebel zu verwenden, der 
zur Entriegelung seiner Rastabschnitte verschwenkt wird. 
Das Verschwenken erfolgt in Steckbewegungsrichtung 
des Stecker- und Buchsenteils. Die Bügelschenkel werden 
dabei auf ihrer dem Gehäusefuß zugekehrten Innenseite von 
Keilen untergriffen, die beim Verschwenken zur Spreizung 
der Bügelschenkel dienen. Zweckmäßigerweise bestehen diese 
Keile aus schräg verlaufenden Wänden einer Außennut, die zur 
Aufnahme der Bügelschenkel des Federbügels dient.

Title: High speed cmos comparator with hysteresis
IPC: H03K5/08
Filed: 1989-05-31
Abstract: A comparator circuit in accordance with the 
present invention includes a first stage (21, 27) which is a 
standard CMOS implementation of a differential 
amplifier. The differential outputs (3, 4) of the first 
stage are applied to the inputs of a second 
differential amplifier stage (32, 35) which is of the same 
design as the first stage. A hysteresis element (31) is 
added to the current mirror load (30, 34) of the second stage 
and is driven by an output (5) of the second stage. This 
second stage output (5) is applied to a threshold matching 
single-ended gain stage (40, 41). The output (7) of the gain stage 
(40, 41) is applied to a standard CMOS inverter (50, 51) which provides 
the final comparator output (8). The hysteresis element (31) is 
placed internally within the second stage (32, 35) to be driven 
by the second stage output (5) such that the voltage 
difference between the differential inputs (3, 4) to the 
second stage must exceed a preselected threshold 
voltage before the output (5) to the single-ended gain 
stage switches state.

Title: Method and apparatus for efficient loop constructs in hardware and microcode
IPC: G06F9/32
Filed: 1989-10-21
Abstract: Method and apparatus to avoid the code space and time 
overhead of the software-loop. Loops (repeatedly 
executed blocks of instructions) are often used in 
software and microcode. Loops may be employed for 
array manipulation, storage initialization, division 
and square-root interpretation, and micro-interpreta­
tion of instructions with variable-length operands. 
Software creates loops by keeping an iteration count 
in a register or in memory. During each iteration of 
the code loop, software decrements the count, and then 
branches to the "top" of the loop is the count remains 
nonzero.  
     This apparatus puts the decrement, compare, and 
branch- to-top into hardware, reducing the number of 
instructions in the loop and speeding loop execution. 
Hardware further speeds loop execution by eliminating 
the wait for the branch to the top-of-loop 
instruction. That is, it prefetches the top-of-loop 
instruction near the bottom of the loop. The loop may 
be initialized for a fixed iteration count, or can 
accept a variable count in the iteration count 
register. The apparatus consists of counters for the 
number of instructions in the loop, an iteration 
counter, a pointer to the top-of-loop location, and an 
instruction to initiate the loop.

IPC: H01B13/00

Abstract: The method of making a flat wiring harness consists 
of a pre-shaping process, a shaping process, and a wire 
bonding process. In the pre-shaping process, the 
intertwined wires are combed to be smoothed and 
straightened out and are pushed by a press block into 
parallelly arranged grooves in a series of longitudinally 
lined jigs and kept therein by a cover. In the shaping 
process, the group of wires thus laid in parallel lines 
in a series of the grooved jigs are shaped into a desired 
pattern of the flat wiring harness by moving any desired 
grooved jigs horizontally along guide slots formed in a 
holder plate, on which the grooved jigs and associated 
components are mounted. In the bonding process, the 
shaped flat wire group is applied with adhesive on one 
side through a screen which is patterned according to the 
shape of a final flat wiring harness. As the adhesive 
hardens, the wires are bonded together and a flat wiring 
harness of a desired two-dimensional shape is obtained. 
This method allows the wires of different sizes to be 
bonded together. It also permits the formation of branch 
wires at any locations from the trunk.

threshold level and at least one other recognizable 
predetermined characteristic, from other received signals 
below said predetermined threshold amplitude, comprising:  
means for combining said received signal of unknown

predetermined amplitude having at least one other 
predetermined characteristic which is distinguishable from 
said other recognizable characteristic of said received 
signal; and  
signal processing means having the combined signal as its 
input and which produces an output signal whose other 
recognizable characteristic is determined by said received 
signal only when said received signal is above said 
predetermined threshold amplitude, and by said known signal 
when said received signal is below said predetermined 
threshold amplitude, whereby the presence or absence of said 
desired received signal may be determined on the basis of 
analysis of said other predetermined characteristic of said 
output signal of said signal processing means.

dently, the molecular weight distribution Mw/Mn of the 
obtained ethylene polymer is in the range of from 7 to 
17 and the rate constant of deactivation Kd at said 
polymerization is larger than 0.3 hr⁻¹.
